Pipe Connector

Abstract

A pipe connector includes a pipe-connecting piece hollowed in its interior, a pipe-covering piece covered on the pipe-connecting piece, and a sealing piece detachably provided on the outside of one end of the pipe-covering piece. The pipe-connecting piece has a first connecting port for communicating with its interior. At least one through hole is provided on the pipe-connecting piece for communicating with its interior. Further, two leakage-proof washers are provided at an interval with the through hole disposed therebetween. The pipe-covering piece has an annular sheath and a second connecting port provided on the outer wall of the annular sheath. The annular sheath is covered on the pipe-connecting piece to allow its inner wall to tightly contact with the two leakage-proof washers, so that the second connecting port is in communication with the interior of the pipe-connecting piece.

       6 . The pipe connector according to  claim 1 , wherein the annular sheath of the pipe-covering piece has a sheath hole penetrating both ends thereof for covering the annular sheath on the pipe-connecting piece. 
   
   
       7 . The pipe connector according to  claim 6 , wherein the sheath hole is a circular hole. 
   
   
       8 . The pipe connector according to  claim 1 , wherein the sealing piece is provided with a penetrating hole thereon, an end face of the pipe-connecting piece is provided with a screw hole to correspond to the penetrating hole, and a locking element penetrates through the penetrating hole and is locked onto the screw hole. 
   
   
       9 . The pipe connector according to  claim 1 , wherein the sealing piece is provided with a clasping portion thereon, an end face of the pipe-connecting piece is provided with a clasping hole to correspond to the clasping portion, and the clasping portion and the clasping hole are clasped with each other. 
   
   
       10 . A pipe connector, comprising:
 a pipe-connecting piece hollowed in an interior thereof and having a first connecting port for communicating with the interior, the pipe-connecting piece provided with at least one through hole for communicating with the interior, and two leakage-proof washers provided at an interval with the through hole disposed therebetween;   a pipe-covering piece having an annular sheath and a second connecting port provided on an outer wall of the annular sheath, the annular sheath having a circular sheath hole, the sheath hole covered on the pipe-connecting piece to allow an inner wall of the annular sheath to tightly abut against the two leakage-proof washers and to allow the second connecting port to communicate with the interior of the pipe-connecting piece; and   a sealing piece provided on outside of one end of the pipe-covering piece and located at one end away from the first connecting port of the pipe-connecting piece.   
   
   
       11 . The pipe connector according to  claim 10 , wherein the pipe-connecting piece is recessed to provide with two annular grooves, the two annular grooves are provided at an interval with the through hole disposed therebetween, and the two leakage-proof washers are inserted into the two annular grooves, respectively. 
   
   
       12 . The pipe connector according to  claim 10 , wherein the pipe-connecting piece is provided with a stopping ring adjacent to an outer periphery of the first connecting port, and one end of the pipe-covering piece abuts against the stopping ring.
